Need a developer who can build your web application and keep it running in production? I build, deploy, and maintain complete web applications on Linux servers — one person, full lifecycle, no handoffs.
I own and maintain two commercial software products sold to multiple clients:
— A gym management system with hardware-based access control serving 4 gyms and 1,200+ active members (Python, C, Vue 3, Laravel)
— A restaurant ordering and delivery platform where one client collected 150+ five-star Google reviews through a smart feedback system I built (Laravel, Vue.js, .NET)
Beyond my own products, I manage 15+ websites and web applications for 10+ clients, handle Linux server infrastructure with less than 12 hours of downtime per year over the last 3 years, and deploy and maintain self-hosted solutions like Nextcloud and Invoice Ninja (customized for Serbian e-invoicing compliance).
What I deliver:
— Full-stack web applications (Laravel + Vue.js)
— REST API development and third-party integrations
— Linux server setup, deployment, and ongoing maintenance
— DNS, hosting, SSL, and production infrastructure
— Self-hosted software deployment and customization
I take full ownership of every project — from first commit to production server — and communicate clearly throughout. If you need a reliable developer who ships and maintains, send me a message with your project details.

I build and ship production web applications end to end: Vue/Nuxt interfaces, Supabase auth and Postgres with RLS, and deployment. With 2.5 years of hands-on experience, I work independently and can own a feature from UI through backend logic to release.
What I deliver
Frontend: Vue 3, Nuxt (including Nuxt 4), Astro, TypeScript — clean components, maintainable structure, complex workflows made clear for users
Backend: Supabase — auth, Postgres, RLS, RPC/backend logic with real security constraints
UI: Nuxt UI, Tailwind, responsive layouts, clear data presentation
Quality: Thoughtful testing, early refactors when needed, code that stays stable as the product grows
Recent projects
Answering-service platform — Interactive pricing calculator (volume discounts), PayEngine checkout, 8-step signup flow. Live product serving real users.
Multi-role operations app — Calendar, invoicing, and scheduling across user roles with reliable date/time handling.
Equestrium — Solo full-stack SaaS for farrier operations (Nuxt 4, Vue 3, Supabase + RLS): auth, stables/horses, visits, scheduling, dashboards, calendar. In beta, iterating on user feedback.
How I work
Efficient and hands-on. I plan before I code, use AI for boilerplate and exploration, and review everything before it ships. I care about architecture and maintainability — not just ticking off tasks.
Good fit if you need someone who can:
Build or extend a Vue/Nuxt product without heavy hand-holding
Implement Supabase auth, database design, and RLS correctly
Turn complex business logic into a clear, usable UI
Own delivery from implementation through production
Based in Serbia. Available for calls during EU and US business hours.
